Johnny was playing outside when he really had to go to the bathroom. He runs in and his grandma was about to take a shower. He looks at her crotch and says, “Whats that?” She says, “Well, it's a beaver, Johnny.”
The next day the same thing happens, only his mom is taking the shower. He says, “Mom I know what that is. It's a beaver, but I think grandma's is dead because it's tongue is hanging out.”
